Abstract

Fouling is an unwanted deposit on a heat exchanger surface which may cause inefficiency to the heat exchanger’s performance in maintaining the outlet product temperature during pasteurization. In order to deal with this problem, fouling must be handled by an efficient control strategy. In this study, an empirical model of fouling was successfully developed and used in a control system. The obtained model is represented by first order plus time delay model with R2 = 0.90. Several proportional-integral-derivative (PID) controllers were then simulated on this model to determine the best control system. Simulation results showed that an ideal PID controller tuned by minimization of integral absolute error (IAE) method exhibited good performance in disturbance rejection of fouling with settling time reduced and robustness improved. This result provides insights to properly design a control strategy dealing with fouling during pasteurization.
